No, DSSS is a modulation process rather than a signal-shielding process. The difference is that differential signalling can be converted to single-ended with a simple subtraction (or other passive techniques), but recovering DSSS requires digital signal processing.

In fact, he's got a nice little simulation of generating a "gold code", adding noise and multipath distortion to it, feeding it through an I/F mixer, quantising it, and recovering the original code. http://www.aholme.co.uk/GPS/SRC/2011/C++/Simulation.cpp
